21. Facebook – Facebook swap shops are great for selling things locally. It’s like CraigsList, but a little easier. You simply search for swap shops in your area and ask to join the group. Once you’re in, take a picture of the item, write a quick description with the price and post it. It doesn’t get much easier than that. You can generally expect to get about what you would get at a yard sale, maybe a little more.
So many people dream of writing a book, but never go through with it. Yet no matter what, I’m sure you have experience and value you could give through writing a book. By packaging your skills and knowledge into a downloadable eBook that helps people learn a skill, advance their careers, or start a businesses, you can change someone’s life and even make good money online.
Online poker is fun. You get to play games for money! I even know a few people that make a lot of money playing online poker. But obviously, I had to list it because it’s interesting to think about. Obviously, there are a few drawbacks to making an income from online gambling. It’s highly addictive, whether you’re good or not. And if you’re not good, you can lose everything very quickly.
Take advantage of tax laws if you're self-employed. Money saved on taxes is still money saved. You may be able to deduct many of your business expenses (use of your home, use of your car, office supplies, etc.) if you keep good records. You may also qualify for tax breaks, such as deducting your health insurance premiums on your tax return. These laws are in place to encourage commerce and business growth, so don't neglect their benefits especially if you want to make money.
People are turning to audio and visuals when it comes to technical subjects. However, you should consider doing an ebook first and turning it into an audiobook through a resource like Audible's ACX platform. You can hire a producer either through a royalty share program, so you don't have to shell out upfront cash, or you can do a pay-per-hour hire as well.
Sell scavenged valuables. If you have a metal detector, or even just a good eye, go to public places where people are likely to drop something unnoticed (such as parks, beaches, and shopping areas), and look for money, jewelry and other valuable goods. This method isn’t very reliable, but you just might get lucky and be able to find something you can sell quickly for cash.
Re-selling web hosting will enable you to make money hosting your own client’s websites. Large hosting companies like HostGator allow you to white label their hosting services. You could start your own hosting business or, if you are a web designer, include hosting into your web design packages. And the best of it is the hosting companies take care of the hosting for you, so all you need to worry about is selling.
Make sure you have some sort of money maker on your website before you start promoting it. You could promote an affiliate product related to your site's topic, or you could use Google Adsense. Your goal is to get your site to make the most money possible, so if you have lots of ways to make money on your site, then you will most likely make lots of money.
Starting a podcast, like making a YouTube channel or blog, comes down to telling interesting stories and building an engaged audience. I’m probably sounding like a broken record by now, but you need a niche that you’re interested in and there’s already a demand for. Come up with a list of topics you’d like to talk about and then search iTunes charts, Google Trends and other podcast research sites like cast.market to see what’s currently out there and popular.
Watch out for inflation chipping away at your assets. We've all heard an elderly person describe the purchasing power of a coin in their day. Inflation continues to make today's money worth less in the future. To win the race against time and inflation, learn to invest your money in the right places. A savings account might help you to keep up with inflation; however, to stay ahead of the game you'll want to invest in bonds, stocks, or some other investment that returns above the average rate of inflation (currently 3%-4%).
Ebay is a bellwether. It's been around since nearly the start of the online boom. But, like any other platform, success can seem fleeting if you don't know what you're doing. Selling items on eBay, professionally that is, can be an art form. Getting people interested in your auctions isn't always easy, especially when there's hefty competition and low demand for what you're selling.
Salvage and resell. Do you love antiques or have a knack for finding valuables at flea markets or yard sales? If you do, it might be time to consider salvaging items for resale – or even scouting out antiques to sell for a profit. While you’ll need to spend quite a bit of time searching for prospects and spend some money buying upfront, you could easily turn a profit if you know what you’re doing.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity. The best thing about selling online courses is that once you do the up-front work in creating the course and setting up your marketing strategy, you can get paid over and over again for work you do once.
